Overview

This node performs a fast port scan on a specified target network range, host, or IP using the nmap command with the -F option. It is useful for quickly identifying open ports on a host within a network. For example, it can be used by network administrators to rapidly check which ports are open on a server or device for security auditing or troubleshooting.

Use Case Examples

1. Scan a single host to find open ports quickly.
2. Scan a subnet to identify devices with open ports for network inventory.
